Definitions

  • This invention relates to hot bowls for cigarette lighters, particularly of the type mounted on motor vehicles, and in particular relates to the method of fixing the spiral resistance element into the hot bowl.
  • a cigarette lighter according to the preamble of claim 1 is known from US-A-1 803 361.
  • the object of the present invention is to fix the spiral resistance element in the hot bowl of the cigarette lighter body in a way that does not present the aforesaid problems and is of simple and inexpensive implementation.
  • a hot bowl for the pusher assembly of a cigarette lighter is disclosed, in particular mounted on motor vehicles and provided with a spiral resistance element connected electrically at two points, wherein the hot bowl comprises a pliable lug on its perimetral surface, characterised in that one end of the spiral resistance element is pinched between said lug and the wall of the hot bowl by a crimping process.
  • the direct crimping of the last turn of the resistance element overcomes said detachment problems arising from unreliable welding.
  • durable and stable fixing is achieved by a very simple operation of very low cost.
  • the reference numeral 1 indicates overall the body of a cigarette lighter of the type mounted on motor vehicles but not shown in its entirety, with which there is associated a hot bowl 2 formed from sheet metal bent into cup shape.
  • a hot bowl 2 formed from sheet metal bent into cup shape.
  • the conductor shaft 5 forms the first of the two electrical contacts to which the spiral resistance element 3 is connected.
  • the second electrical contact is provided by the connection of the second end 7 of the spiral resistance element 3 to the inner wall of the hot bowl 2.
  • the second connection is made by crimping a lug 8 integral with the lateral wall of the hot bowl 2, by bending said lug over so that it pinches the end of the spiral between itself and the inner wall of the hot bowl.
  • the procedure consists of a first stage in which a flat sheet metal disc is formed by blanking. Said disc is then punched to obtain a U-shaped aperture close to the outer wall of the disc.
  • Said aperture defines the lug 8 which is later bent over to lock (by a crimping procedure) the outer end 7 of the spiral 3.
  • the external shape of the cup-shaped hot bowl is then obtained by deep-drawing. At this point the spiral is inserted into the hot bowl and crimping is then effected in the aforesaid manner by bending the lug over.
  • the conductor shaft is then inserted into the hole and fixed to the other end of the spiral resistance element 3.
  • the lug 7 can be formed by different methods without leaving the scope of the present invention.
